Description

[Detailed description of the invention] This invention involves attaching an automatic winding shaft or fixed crosspiece to one end edge of a flexible shield such as an insect screen, sunscreen, or partition sheet, and attaching an automatic winding shaft or fixed crosspiece to the other end of the shield is an opening shielding mechanism consisting of a movable crosspiece that is movable along a guide frame, and the movable crosspiece is fixed so that the shield can maintain its shielding state even when the shield receives external force such as wind. A new temporary locking device for the above-mentioned shielding mechanism is provided, which allows the crosspiece to be attached to and detached from the receiving frame attached to the pillar of the opening with a simple operation, and the locking condition can be adjusted extremely easily. This is what we are trying to provide.

Conventionally, as a temporary locking device for this type of opening shielding mechanism, for example, a plurality of magnets spaced apart from each other on the movable crosspiece are attached to an iron piece attached to a pillar of the corresponding opening. There was a method to lock these by adsorption, but in this case, if the above-mentioned shield was short or eye-opening to the opening, its tensile force would be strong, and it could not be moved even by a slight external force. Since the crosspiece is pulled away, it becomes impossible to shield the opening, and conversely, if the attraction force of the magnet is too strong, it is very troublesome and difficult to separate the movable crosspiece from the pillar etc. when a person enters or exits the opening. In addition to the inconvenience that may occur, when fixing the above-mentioned iron piece to the pillar, it is possible to make a mistake and attach it with wood screws etc. at a position that is out of alignment with the above-mentioned magnet.
At this time, it was difficult to reattach it, and it also had various drawbacks, such as leaving scars on the pillar.

This invention improves the above-mentioned drawbacks, and makes it possible to engage and disengage the movable crosspiece and the receiving frame with a simple operation, and also makes it extremely easy to install these devices and adjust the locking condition. In order to do this, the movable crosspiece is provided with a locking body which is biased in one direction by a spring and has a curved hook portion having a substantially sickle-shaped side surface at one end of the biased side. The locking body has the shaft tips of each lever pivotally connected to the front and back of the movable crosspiece so that it can swing freely, and a receiving frame that is fixed to a pillar of the opening facing the locking body. is provided with a pair of fixing plates which are fixed with attachment edges provided facing each other on the inner surfaces of both side plates, and one of the fixing plates has a retaining edge that engages with the above-mentioned hook. The present invention provides a novel temporary locking device for the above-mentioned mechanism in which a stop piece is provided in a protruding manner to improve various drawbacks of the conventional device.

Next, one embodiment of the present invention will be explained based on FIGS. 1 to 5. The insect-proof shielding mechanism M attached to the opening S of a house is a self-winding mechanism that is rotatably housed in a fixed frame 1 whose one end edge of the shield 2 is fixed to a pillar Sa on one side of the opening S. The shield 2 is fixed to a shaft (not shown), and the other edge of the shield 2 is attached to the upper frame of the opening S.
It is fastened to the end of a movable crosspiece 4 which is movably provided along a guide frame 3 fixed to Sb by means of edge retaining material 15. In addition, a receiving frame 5 is fixed to the pillar Sc on the other side of the opening S at a position corresponding to the movable crosspiece 4, and side plates 5b and 5'b for guiding are provided opposite to the receiving frame 5 on both sides of the mounting board 5a. The end portion of the movable crosspiece 4 is loosely fitted into the movable crosspiece 4. Furthermore, on the front and back surfaces of the movable crosspiece 4, a pair of pulls 6, 6' and upper and lower seat plates 6a, 6b and 6'a, 6'b, which are integrally provided respectively, are provided with screws passing through the movable crosspiece 4, respectively. 14,14
are screwed together and fixed. Of these seat plates, each of the seat plates 6a and 6'a has a prismatic square shaft 9a at the tip of the shaft at a position facing each other.
Levers 9, 9' provided with 9'a are pivoted to face each other, and these square shafts 9a, 9'a are connected to the movable bar 4 through holes bored in the side walls 4b, 4'b of the movable bar 4. The levers 9, 9' and the locking body 7 are inserted into the recessed groove 4a of the locking body 7 and are respectively fitted into the square shaft hole 7b formed at one end of the locking body 7, so that the levers 9, 9' and the locking body 7 are integrally connected to each other. This locking body 7 is biased in one direction by a spring 8 in the direction opposite to the direction of the levers 9, 9'.
Further, a curved hook portion 7a having a substantially sickle-shaped side surface shape is formed at the tip of the biased end. This locking body 7
There is a partition wall 4c of the movable crosspiece 4 near the square shaft hole 7b.
A rotation stopper 7c is provided which comes into contact with the locking member 7 and the levers 9, 9' are kept in a horizontal position, but they are rotated in a predetermined direction against the elastic force of the spring 8. It is configured to be swung by an angle (α° in the figure). On the other hand, a pair of mounting edges 5c, 5'c are protruded from opposing surfaces of both side plates 5b, 5'b of the receiving frame 5 at positions slightly apart from the mounting board 5a. Further, on the front and back surfaces of the mounting edges 5c and 5'c, a front side fixing plate 11 and a back side fixing plate 12, which are slidably fitted between the side plates 5b and 5'b, are provided facing each other. , these fixing plates connect setscrews 13, 13 inserted through holes 11a, 11a provided in the front side fixing plate 11 to the back side fixing plate 12.
They are each screwed into screw holes 12a, 12a provided in the screw holes 12a and 12a, respectively, and can be mutually tightened and loosened. Also, this front side fixing plate 11
A retaining edge 1 that is engaged with the curved hook portion 7a is provided on the upper part of the
A receiving piece 10 having a diameter of 0a is provided in a protruding manner. The height of this snap edge 10a is set so that it can easily engage with the curved hook portion 7a of the lock body 7 when the movable crosspiece 4 is brought into contact with the receiving frame 5. It is fixed to the receiving frame 5 in line with the indication line 7d provided on the side surface of the frame 7. In addition, 16 is a buffer body fixed to the edge of the movable crosspiece 4.

This device is constructed as described above, but to explain its operation now, force is applied to the puller 6 in the direction of pulling out the shield 2 wound up on the automatic winding shaft of this shielding mechanism M from the fixed frame 1. When the movable crosspiece 4 is moved along the guide frame 3 and loosely fitted into the receiving frame 5 provided on the other side of the opening S, the entire surface of the opening S is covered by the shielding body 2. It will be done. At this time, when the movable crosspiece 4 is pulled all the way so that the buffer body 16 fixed to the edge of the movable crosspiece 4 comes into contact with the mounting board 5a of the receiving frame 5, the tip of the locking body 7 is brought into contact with the receiving frame 5. Attached locking piece 10
However, since the tip of this locking body 7 is a curved surface, the tip of this locking body 7 is lifted up against the elasticity of the spring 8 as the movable crosspiece 4 moves. After passing the end of the curved surface, the movable bar 4 is suddenly pushed down and the curved hook portion 7a and the stop edge 10a are engaged with each other, so that the movable bar 4 is locked to the receiving frame 5. To release the engagement with the movable crosspiece 4 locked in the above manner, when force is applied to the lever 9 or 9' with a fingertip, the curved hook portion 7a is lifted up against the elasticity of the spring 8 and released from the locking edge 10a. Although he leaves,
At the same time, the movable crosspiece 4 leaves the receiving frame 5 and moves toward the fixed frame 1 by itself due to the shield 2 which is constantly pulled toward the fixed frame 1 by the action of the automatic winding shaft.

The above is an explanation of the case where the temporary locking device of this invention is implemented in a shielding mechanism having an automatic winding shaft. Even when implemented in a folding shielding mechanism that is fixed to a 7 and the catch piece 10 are still engaged with each other, and in this case, to release the engagement, push down the lever 9 or 9' with your thumb, etc., and press down on the handle 6 or 9' with your other fingers. All you have to do is move 6' in the opposite direction to the receiving frame.

In the above embodiment, for example, if the retaining edge 10a of the receiving piece 10 is too high relative to the curved surface of the retaining body 7, even if the movable crosspiece 4 is pulled toward the receiving frame 5 side, the curved hook portion 7a will not easily move. It is extremely important that the height of this retaining edge 10a is always fixed at an appropriate position, as it will not be pushed up and therefore cannot be engaged, and conversely, if it is too low, it will become unnecessarily easy to disengage. It is. Therefore, in the above embodiment, for example, the retaining edge 1
If it comes off at an unnecessary time because 0a is low, first move the movable crosspiece 4 away from the receiving frame 5,
Use a screwdriver etc. to tighten the set screws 13 of the fixing plates 11 and 12.
13 and then move them as necessary, the retaining edge 10a provided on the receiving piece 10 on the upper part of the front side fixed plate 11 will also move, so check whether the moved position is appropriate or not together with the movable crosspiece 4. After approaching the curved hook portion 7a and checking it, the set screws 13, 13 are tightened again to complete the adjustment of the engagement state.

In the above embodiment, the receiving piece 10 is the front side fixing plate 11.
This receiving piece is provided on the top of the 1 shown in Figure 6.
0, it may be provided on the upper part of the back side fixing plate 12.

Furthermore, the locking body 7 of the above embodiment has square shafts 9 provided in the square shaft hole 7b on the front and back levers 9, 9', respectively.
a, 9'a were fitted together to connect them together, but as shown in FIG. Square shaft holes 9a, 9'a in levers 9, 9', respectively
They may be integrally connected by providing them and fitting them together, and as shown in FIG. B is front and back lever 9,
The square holes 9b and 9'b provided in the respective holes 9' may be fitted into each other and connected as one body. Furthermore, the above-mentioned square shaft and square shaft hole do not necessarily have to have a square cross section, and it is sufficient to have one flat portion in the axial direction at one location on the circumferential surface.

As explained above, according to the temporary locking device of this invention, conventionally in this type of opening shielding mechanism, a plurality of magnets fixed to a movable crosspiece and the same number of iron pieces fixed to a pillar etc. are attracted to each other and engaged. If the magnetic force is weak, the movable crosspiece will easily come off due to external forces such as wind pressure applied to the shield, whereas if the magnetic force is strong, the movable crosspiece will be pulled away from the pillar when people enter or exit. In addition to being extremely troublesome and difficult to operate,
If this iron piece is installed incorrectly, it will take a lot of effort to reattach it, and moreover, it will leave a scar on the pillar, which has many disadvantages, and this will eliminate all the problems.

That is, according to the present invention, the movable crosspiece is attached to the receiving frame by the engagement of the curved hook portion and the retaining edge, so even if the shield is short or wide, the movable crosspiece can be easily moved due to wind pressure, etc. There is no chance of it coming off, and when a person enters or exits, they can simply push the lever down slightly with their fingertips, or push down the lever with their thumb and move the handle laterally with their other fingers. It is possible to release the engagement without applying any particularly strong force, and conversely, when locking these, simply pressing the movable crosspiece against the receiving frame is enough to prevent people from entering or exiting this shielding mechanism. This makes the operation of engaging and disengaging the movable crosspiece very easy.

Furthermore, in a temporary locking device using a locking body having a curved hook portion as in this invention, if the height of the locking edge of the catch piece is not appropriate for the curved surface of the locking body, the good quality of the locking device may deteriorate. However, in this invention, the locking body, which is assembled by connecting many parts, is fixed in a predetermined position in advance, and the locking piece with a simple configuration is used. Since the position of the lock can be adjusted extremely easily with a screwdriver, etc., the adjustment of the locking condition can be done at any time and can be done extremely easily, and this operation does not leave any scars on the pillar etc. In addition, many practical values can be obtained, such as the fact that these devices can be assembled and installed on-site extremely easily and quickly.
